I'm just curious if it was a f-up by the interim or new admin(s)...
No...I don't think so. In the past, when the site when down (and the server had to be re-booted), Craig was all over it. Right now, there is no one.
It may have been the hosting company that brought it back up? The data could still be there, but the address is not pointing it in the right direction. Either way, data loss is not good.
There were plans to re-do the site, including integrating all the content (like OSO). I saw an early version, and it looked really cool. However, when Craig left, so did all his work to get it implemented.
